General information

  Stalker is a hang-glider with a rigid wing of new generation. The original wing design have provided its high rigidity and low drag. At the midlle-sized span, Stalker has got good perfomaces in a wide speed range, it is faultlessly stabilized and controled easily. High-speed cross-country flights are its main element. As for recreation it will present comfort and safety.
  Unique characteristics of the Stalker as a new generation rigid wing are as follows:
  • Aileron control (unlike spoileron control on the similar gliders offered by other manufacturers);
  • Split Aileron Drag Device (SPADD) - dragging control surface at the wing tip, designed to counteract adverse yawing;
  • Gelcoated D-cell makes the leading edge ideally smooth and reduces air drag;
  • An admirable conjunction of the dacron sail with carbon fiber D-cell. Optimized design of the cabon fiber D-cell and rigid wing tip ensure the necessary rigidity of the wing in flight, which is important for avoiding tumbling and spin. 
  The most amazing feature of the Stalker is its extremely easy handling and feeling of comfort in flight. All pilots who have had a chance to fly it marked that handling of the Stalker is similar to that of a hang glider, but requires much smaller pilot input.

 Even having completed the development and certification of a generally successful glider we never stopped searching for and introducing new solutions into its design. The result of this search has become a modification - Stalker II, which includes 10 changes, the most essential of them being as follows:
  • Winglets;
  • New SPADD design with the view to improve performance and appearance;
  • New control frame minimizing air drag, including carbon fiber basebar with improved aerodynamic profile and rounded corner brackets decreasing interference drag at the points where the basebar is attached to the downtubes, as well as carbon fiber downtubes which can easily be replaced by aluminum downtubes;Optimized design of ribs and keel beam for weight reduction;
  • Optimized design of ribs and keel beam for weight reduction.
  • Changed design of flaps and ailerons to reduce the step at the place where they are attached to the main wing.

  Improvement of performance was so essential that this was immediately noticed by pilots. Comparisons with the best gliders of this class showed that Stalker was at least equal to them in climb and at low speed and had a significantly better performance at higher speed. Here we'd like to mark that the research in the sphere of optimization of the soaring flight show that for getting the maximum speed in a cross-country flight and for achieving maximum flight range for breaking records a sailplane or a hang glider must fly at a speed higher than the maximum performance speed. The best aircraft proves to be the one which, even if having a slightly lower max. performance, has advantage at higher speed.
  Another important feature of the Stalker modification is that any owner of the previous version of the glider can upgrade his Stalker to the latest version at home.
